There is an other AOT thread `TrainingReplayThread` (also JavaThread) which has loop to process AOT dependencies for classes which were initialized.
And we have 2 AOT compiler threads (for C1 and C2) to load AOT code.
As you see we have specialized threads for AOT work. 

May be I can use this AOTthread for AOT code preloading (AOTCodeCache::preload_code()) which is currently done in main thread.
